I might add FIM and FIA records set at Bonneville also are considered for club membership... currently the board decides in cases where the vehicle may also meet the class requirements for an established SCTA record. I think in those cases it must exceed the SCTA record.
Is it easier... not really... those orgs get more room to run but have turn around requirements.
I usually explain it to folks like this... all you have to do is set a record over 200 and go faster than anyone else has since 1953... But there are some minimums for added and split up classes...
So guys like Chris Carr had to go over 350 MPH to get in the Club... and if you are building a Streamliner it is possible you will have to go over 400 to get in the 200 MPH club....
